Chemistry Stoichiometry - Free Essay Examples and Topic Ideas

Chemistry stoichiometry is a branch of chemistry that deals with the quantitative relationships between the reactants and products in a chemical reaction. It involves the use of the mole concept and balanced chemical equations to determine the amounts of reactants that are needed, the amounts of products that are formed, and the limiting reactant in a reaction. The calculations are based on the law of conservation of mass, which states that matter cannot be created nor destroyed in a chemical reaction. Stoichiometry is important in understanding and predicting the outcomes of chemical reactions in various fields of study, including industrial chemistry, environmental chemistry, and biochemistry.

    Introduction: The fascinating world of metallurgy and coinage intertwines in the analysis of U.S. Mint ten-cent dimes, specifically those minted before 1965. These historical coins, once composed of a unique alloy of silver and copper, hold not only monetary value but also serve as artifacts reflecting a bygone era. This study embarks on a comprehensive exploration, utilizing the precision of gravimetric analysis to unravel the percentage composition of silver in these pre-1965 dimes, providing insights into their material makeup and…

    The calculations completed for this experiment include determining the amount of Na2CO3 needed to do a full reaction. This was calculated through stoichiometry calculations: Molar mass was first calculated for CaCl2*2H2O Ca = 40.078g Cl2 = 35.453g*2 = 70.906g 2H2 = 1.00794g*4 = 4.03176g 2O = 15.9994g*2 = 31.9988g 40.078g + 70.906g + 4.03176g + 31.9988g = 147.01456g or 147.0 g CaCl2 1g CaCl2 * 2H2O x (1 mol CaCl2 *2H2O/147g CaCl2 *2H2O) = 0.0068 mol of CaCl2*2H2O Molar mass…

    Abstract: In this experiment Stoichiometry of a Precipitation Reaction, the main objectives were to use stoichiometry to calculate the theoretical yield of CaCO3 that precipitates from the reaction between Calcium chloride, Dihydrate and Sodium carbonate, and then compare that value to the actual yield. In order to do this accurately, we must be able to measure the products and reactants with accuracy. The last objective of this experiment is to calculate the percent yield of the product produced. When 1.0…

    Abstract: A 42.89% yield cyclohexene was successfully synthesized from 10.0 mL cyclohexanol by unimolecular elimination (E1) through the dehydration of cyclohexanol and confirmed via a bromine test and the IR spectra. Introduction: Alkenes are hydrocarbons that have carbon–carbon double bonds and are one of the many functional groups in organic molecules. Alkenes are sp2 hybridized and are unsaturated because two of their hydrogen’s are missing from the saturated alkane formula (CnH2n+2). Typically alkenes are synthesized by elimination reactions, however, organic…
